Functional roles of membrane glycoprotein CD36

Cell-cell and cell-extracellular matrix interactions are mediated by a number of membrane glycoproteins. On the basis of structural homologies, several families of cell adhesion molecules (integrins, selectins, immunoglobulins, cadherins, leucine-rich glycoproteins) have been established. Since 1991, a new family of CD36-like proteins has been identified. CD36 is a cell surface glycoprotein that interacts with a large variety of ligands. CD36 has been implicated in thrombosis, vascular biology, lipid metabolism and atherogenesis. In this review, we aim to summarize our present knowledge on this important, multifunctional glycoprotein.
